Discs not showing up during USB installation, are already formatted

[krel99]

Hi, I am attempting to install Elementary OS from a USB flash drive on my machine Acer TC-1660 along the Windows.

During installation, I can properly test the system from the flash disc. But when I choose to install, I can see only the Flash Drive and no other discs.

I even used EasyUS Partition Master to preformat a partition of the D drive as ext4.
I used the shutdown command in the Windows terminal to fully disable Windows.
As far as I know from discussions with Bard and ChatGPT, there isn't anything in BIOS that should prevent Linux from recognizing the discs.

Please help!
I will provide any other necessary information, should it be requested.

I solved it myself. It is caused by INTEL's RAID technology which sets disc's communication in BIOS
